Why can two igneous rocks have the same minerals but different names?
-The rocks may have different textures.
-The rocks may be of different sizes.
-The rocks may have different colors.
-The rocks may be found in different areas.
Answer:
The rocks may have different textures
Explanation:
If we have to igneous rocks, and they have the same minerals, that doesn't necessarily means that they will have the same name, thus being classified as the same rock. The reason for this is that the two igneous rocks may have a different texture. One of the rocks may have a foliated, while the other may have porphyritic, giving them different appearance despite the same minerals being in both of them. The reason why two igneous rocks with the same minerlas may appear different, is the process in which they have been formed, the quickness of the cooling, the temperature that they were exposed to, and the pressure they were exposed to.
Answer:
they have different textures
Explanation:

The pea has a haploid number of seven chromosomes, the diploid number would be
Answer:
14
Explanation:
The diploid number is the haploid number times 2.
Answer: It would be double
Explanation: The diploid cells are the cells that have a double number of chromosomes, that is, they have two series of chromosomes. For example, if the pea has an haploid number of seven chromosomes the diploid number should be fourteen chromosomes.
To explain a bit more, the somatic cells of the human being contain 46 chromosomes; that is the diploid number. So, the diploid cells are the cells that have a double number of chromosomes, that is, they have two series of chromosomes. But, in the process of meiosis the reproductive cells will have finally, the haploid number of 23
scientists discovered that new molten materials from inside the eath create new
Answer:
Crust
Explanation:
According to the recently given theory, The theory of Seafloor Spreading the magma or lower most part of the earth's surface which sometimes bursts as (molten lava) plays substantial role in the formation of new crust. This is because when magma or molten lava from the bottom most part of the earth reaches the surface of earth, it cools down and pushes the already existing surface of the earth like rocks from both directions. This pushing of rocks cause the formation of new crust by the molten materials when it cools down.

When did oxygen levels start to decline from 35 percent down to today's levels during what period
about 95 million years ago, during the Carboniferous Period
Answer:
During Carboniferous period, part of the late Paleozoic era.
Explanation:
In the geological story oxygen levels have been relatively stable for the las 200 million of years, but 300 million ago there was a dramatic spike in Oxygen levels until 35% in the Carboniferous , next it plunged in 15 percent in the Triassic, 100 million years later. The growth of the forests removed huge amounts of carbon dioxide from the atmosphere, leading to a surplus of oxygen. The higher oxygen concentration is related with the presence of larger bodies in reptile and insects.
What is responsible for the uneven heating that drives wind and ocean
currents from day to day?
O
A. Earth's tilt
O
B. Microclimates
O
C. Precession
O
D. Earth's revolution
Answer:
A
Explanation:
The earth is tilted at an average of 23.5 degrees. This means that in some seasons, the north pole is tilted towards the sun and in some seasons it is tilted away from the sun. The sun seems to vary in position over an year as the earth revolves around the star. The sun, therefore, variably and differentially heats the regions of the earth. The regions that are heated more form low-pressure system that drives winds.
the answer is , earth's tilt.
Two species of guppies show different mating behaviors is it prezygotic or postzygotic isolation
Answer:
Prezygotic
Explanation:
Prezygotic means that the two species cannot reproduce a viable offspring before the two zygotes meet. Since behaivoral isolation is listed under being prezygotic because behaivors prevent their intercourse before the zygotes meet, then it is prezygotic.

Experiments in which all variables are identical except for one are called _____ experiments
Answer:
Controlled experiments
Explanation:
Controlled experiments are those experiments where all variables are identical but only one is different. The purpose of such experiments is to test a hypothesis by analyzing the change it brings to results due to change of only one variable when everything else is constant. SO we can say that in such experiments, it is the only changing variable which is influencing the results of an experiment because everything else is just same.

Where do homologous chromosomes exchange genetic material through crossing over? A. Centrosomes B. Centromeres C. Chiasma D. Chlorophyll
Answer:
A. Centrosomes
Explanation:
Homologous chromosomes exchange genetic material through crossing over Centrosomes.
ANSWER:
The correct option is C: Chiasma. Homologous chromosomes share genetic information in chiasma during crossing over.
EXPLANATION:
Chiasma is basically a point of contact or a physical link between two chromatids. These chromatids belong to homologous chromosomes and any genetic information can be exchanged at this point of contact. This exchange takes place generally during meiosis rather than mitosis. The exchange of genetic information and material via the chiasma brings about chromosomal segregation in a proper manner.who discovered cell ? and when it was discovered?

The goal of a statement of purpose is:
A. to explain why an experiment is being done.
B. to make accurate measurements.
C. to record observations during an experiment
D. to testa hypothesis.
Answer:
pretty sure its D
Explanation:
The goal of a statement of purpose in a scientific experiment is to explain why the experiment is being conducted. It involves defining the specific problem or objective the experiment seeks to address, leading to the formulation of a hypothesis which will later be tested through the experiment's design, option A is correct.
The goal of a statement of purpose in the context of scientific experiments is to define the primary reason or objective behind conducting the experiment. Typically, this involves outlining the specific problem or question the experiment seeks to address, which leads to the development of a hypothesis. The statement of purpose serves as a guidepost for designing the experiment, ensuring that the methods, measurements, and observations are aligned with testing the hypothesis.
In the scenario provided, the correct answer to the question is A. to explain why an experiment is being done. This is because before moving forward with the experimental design and especially before making any measurements or observations, it is critical to understand the why—the purpose—of the experiment. This clarity informs both the approach to the experiment as well as the interpretation of the results that follow.
A statement of purpose is not primarily about making accurate measurements, recording observations, or testing a hypothesis, although these are also critical components of the scientific method. The statement of purpose is meant to establish the raison d're of the entire process—a narrative that communicates the experiment's objectives to others and sets the stage for the subsequent steps.
Which of the following correctly compares steroid and nonsteroid hormones
Answer:
do post complete question
A steroid hormone is a steroid that acts as a hormone. Steroid hormones can be grouped into two classes: corticosteroids and sex steroids. Within those two classes are five types according to the receptors to which they bind: glucocorticoids, mineralocorticoids, androgens, estrogens, and progestogens.
Nonsteroid hormones (water soluble) do not enter the cell but bind to plasma membrane receptors, generating a chemical signal (second messenger) inside the target cell. Five different second messenger chemicals, including cyclic AMP have been identified. ... The action of nonsteroid hormones.

Plants absorb nitrogen from: the atmosphere the soil water
Answer:
Plants absorb nitrogen from: the soil ( second choice)
ANSWER:
Plants absorb nitrogen from the soil.
EXPLANATION:
Nitrogen is absorbed by the roots of the plants in the form of amino acids, nitrate or nitrite ions. The nitrogen absorbed from the soil by roots is then transported to the various parts of the plants. Plants do not get nitrogen they need directly from the air. This is because the organic nitrogen that is available in the atmosphere is not usable for plants. Plants need non-organic nitrogen which is obtained by changing organic nitrogen into non-organic forms by the bacteria in the soil.Earth’s view from space is like a sparkling blue oasis in a black sea of stars. True Or False
Answer:
True. Since the amount of ocean we have on the planet is 75%, be mostly just see blue when looking at the Earth.
Answer: True
Explanation:
The view of Earth from the space is like a sparkling blue oasis in a black sea this is because the maximum part of the earth is covered with water which constitutes to about 75%.
Rest of the 25% is the land area which appears to b blackish brown in color. The space from where the earth is being seen is very far so it appears like this.
From that 75% only some part is freshwater source which is used by the human beings for its consumption but rest of the water is ocean and marine water which is not suitable for consumption.
18. In replication of DNA, the helix is opened and what is unzipped?
A. Nitrogen bond
C. Oxygen bond
B. Hydrogen bond D. Phosphate bond
Answer:
B) Hydrogen Bond
Explanation:
Those are the bonds that the restrictive enzymes unzip and the bonds that hold the complementary bases.
Final answer:
In DNA replication, helicases unzip the DNA molecule by breaking the hydrogen bonds between the nitrogenous base pairs.
Explanation:
DNA replication is a process that involves the unzipping of the DNA molecule. During this process, enzymes known as helicases break the hydrogen bonds between nitrogenous base pairs. This action separates the two strands of the DNA double helix and allows each strand to serve as a template for the creation of a new complementary strand. Consequently, the letter corresponding to the correct answer is B. Hydrogen bonds between complementary bases break during the replication of DNA.

To visualize the structure of DNA, which has a width of 10 nm, which microscope would be best
Answer:
Electron microscope
Explanation:
Instead of using light, it utilized a beam of electron for illumination. Because an electron beam has a shorter wavelength than light (up to 100, 000 times shorter), they have a higher resolution power and are therefore able to view sub-cellular structures including DNA.
Answer:
The answer is: Electron microscope.
Explanation:
To obtain the maximum magnification and the best resolution, the electron microscope must be used, which can reveal details of up to a few nanometers (nm).
When the thin cuts are sectioned, stained and observed with the electron microscope, a delicate membrane, about 5 nm thick, that surrounds the cell is visualized.
The answer is: Electron microscope.
Discuss the scientific evidence that supports the idea that sexual orientation is greatly influenced by biology.
Answer: It's in the blood
Explanation: Sexuality is usually influenced by Biology because, sexual attraction; or love in this case, is usually brought on from genes passed on from previous generations,Sexuality can also be influenced by a parent with their preferred sexuality.
Answer:
It can be said that science implies that there is a difficult interaction between biological factors, which conditions when a person is attracted to people of the same sex, the opposite sex or both.
Explanation:
The scientific evidence identifies five possible chromosomal regions, in these variants it is shown with a significant frequency that the individuals of a sample that comment have had relations with individuals of the same sex. Although it is noted that the link between biology and homosexual behavior is very complex, since different variants appear that are different between men and women, and without an association between the presence of these genes and a high or low proportion of homosexual relationships.

Liquids and proteins are both types of what?
Answer:
they are classes of food
Explanation:
liquid are water
Liquids and proteins are both types of matter. Proteins, composed of amino acids, are typically either globular or fibrous and have critical functions within organisms. Liquids are a state of matter with definite volume but changeable shape.
Explanation:Liquids and proteins are both types of matter. Matter can exist in various states, including solids, liquids, and gases. Most proteins are either globular or fibrous and play critical roles in organisms. They are made up of chains of amino acids and serve various functions in the body. Globular proteins are soluble in water and have a spherical shape. Examples include hemoglobin in blood and egg albumin from egg whites. These proteins play major roles such as transporting fatty acids and maintaining a proper balance of osmotic pressures in the body.
Liquids, on the other hand, are a state of matter that has a definite volume but can change shape depending on the container. Unlike solids, the molecules in a liquid are not fixed in place and can move with respect to each other. Like gases, they are considered fluids as they yield to shearing forces.

Final answer:
A. Cis polyunsaturated fatty acids lead to the most liquid lipids because their kinked shapes prevent tight packing, making them fluid at room temperature.
Explanation:
The type of fatty acid that would result in a lipid that is the most liquid is A. Cis polyunsaturated. This is because cis polyunsaturated fatty acids have kinked shapes due to the presence of multiple cis double bonds, which prevent them from packing tightly together, thereby lowering their melting point. As a result, lipids composed of cis polyunsaturated fatty acids are more fluid and remain in a liquid state at room temperature compared to their saturated, trans polyunsaturated, and monounsaturated counterparts. Examples of these fatty acids include saturated fatty acid (e.g., stearic acid), polyunsaturated fatty acid (e.g., linoleic acid), and monounsaturated fatty acid (e.g., oleic acid).
